g2. The sexies of being rotated in the directions indicated by arrows and the arrangement being such that the goods entering between the upper roll and the upper chamber pass in a sinuous Acourse from a guide 31 to the table 30 in coi1 tact -with 'extended ironing surfaces. One side of the goods is ironed twice, irst by the roll 18 and chamber 25, and then by the roll 22 and chamber 27, this being called the right side'and having a higher 'polish than.

the opposite side, which is ironed vbut once, and by the roll 20 and chamber 26. The

axes of the series of ironing rolls are not in Vcated by Figs. 1 and 'the same vertical plane, but are in a plane about the angle indi- 4. This arrangement reduces the height of the machine, and causes the goods to-pass from one chamber andV roll to the next in the sinuous path -described without liability of being folded and wrinkled. The goods'are guided to the foldwhich is inclined at ing table 30 by the rear edge of the chamber' 27 as already described and are deposited right side downward on the table so that the attendant is enabled to fold the goods right side out, as is customary, by raising opposite ends of each piece from the table, and

turning them inwardly upon intermediate` resents a larger gea.' journaled in av fixed bearing 42 (Fig. 2 smaller gear 39. 40 is attached a pinion or small gear 43. 44 represents a lever fulcrumed on a shaft 45 supported in fixed bearings 46 on the frame and meshing with the members 12. The longer arm of the lever 47 tht- 44 is provided with a segmental rack meshing with the small gear 43. To shorter arm of the lever 44 is pivoted 48 a shoe 49 which supports the lower steam chamber 27. There are two levers 44, each having a shoe`49, said shoes being located at or near 'opposite ends of the chamber 27.

The rotation of the operating shaft 33. by the hand wheel 35 causes the levers. 44 to swing on their ulcrums and .raise orv lower the shoes 49 and the lower steam chamber 27 sup orted thereby, provi 'on being thus made or vertically moving t e chamber 27 away from the lowe'r roll 22 when the machine is not in use.

, The described movement of thelevers 44 is utilized to move thebearings 15 and 16 Fig. 2) and provided at To the shaft 41 of the gear simultaneously inopposite directions and in substantially horizontal paths to move the upper roll 18 toward and from the chamber 25 and the intermediate roll ,201 toward and from the chamber 26, the levers 44 being connected with the sliding bear-I ings' 15 and 16 by the means next described.

50 represents a bell crank lever pivoted at 51 to the frame and having a slot 52 in one of its arms engaging a stud 53 on an 75 Aear attached to the upper bearing 15. The

other ai'm of the lever 50 is pivoted at 54 to one end of a connecting rod 55, the other end of which is connected by a stud 56 with an ear on the lever 44, said ear having a. slot 57 in which the stud 56 is movable. 58 represents another bell crank lever pivoted at -59 to the frame and having a slot 60 in one of its arms receiving a stud 61 attached to an arm on the sliding bearing 16. To the other`arm of the lever 58 is pivoted at 62 a link 63, the'other end of which is pivoted at 54 tothe lever 50 and to the connecting rod 55. It will now be seen that an upward movement of the lever 44 causes the 90 bell crank levers 50 and 58 to swingsimultaneously in the directions required to move the upper roll 18 toward the left and the intermediate roll 20 towardthe right from the positions indicated in Fig. 4, said rolls being therefore simultaneously separated or moved away from the corresponding chambers 25 and 26. It will of course be understood that the boxes l5 and 16 at each end of the machine are adjusted in the manner and by the means above described.l there being two sets of bellcrank levers 50 and 58.

It is obvious that 'a downward movement of the levers 44 will cause the rolls 18 and 2 0to move toward the corresponding chain- 105 bers 25 and 26. i

The lower steam chamber 27 is loosely connected with the shoes 49, said chamber having a curved projecting bearing face 65 resting` on a ycurved seat 66 formed on the 110 shoe 49 between two stop shoulders 67, which are arranged as indicated by Figs. 1 and 4 to permit limited movement of the face 65 between them. The seat 66v and face 65 are concentric with the concave 115 pressing .face of the chamber 27. The.levers 44 and shoes 49 constitute a simple and ef?- fective means for adiustably supporting thel chamber 27. The obj ect of the described loose engagement between the chamber 27 and the 120 shoes 49 is to maintain the concave pressing face 'of the chamber 27 substantially parallel or concentric with the periphery of the roll when the chamber 27 is adjusted vertically. To the ends of the chamber 27 are 125 pivoted at G8 links 69. the oiitei'rgends of which are pivoted at. 7() to the fraaie. rThese links prevent the chamber 27 from tipping on the shoes 49, so that when the machine is at rest and .he chamber 27 is retracted n0130 bearings es shown by Fig. G.

" insegne 'of the heatedlchember can touchthe of the thrended `sections will increase or Idecrease the length ot the said connecting rods and links, provision' being thus mede tor'independently adjusting or varying the initial positions of the rolls 18 and 20 and `cli-timber 27.

.l have found that there is Sometimes a tendency of the goods to. cling to the cloth cover of the upper roll 19, the goods conteining more moisture et this part than in subsequent parts of their path through the machine.' To overcome this tendency l provde the chamber 25 1with a rib or bead 72 projecting from the concave fece ot' the chamber end, having n rounded surface adapted to .compress .the goods passing be tween it and 'the roll 18 and et the same time compress the `cloth covering 2lioi the roll.

Ars the covering passes the bead 72 its effort to expend ,loosens the goods from the cloth cover and counteracts the tendency ot the goods to cling tothe cover. Each of the steam chambers may be provided with a bend or projection for this purpose if desired.

The sliding bearings 15 and 1.6 rest on antifriction rollsy 75 interposed between the beer-ings and their lovver guides, as shown by Figs. l, end 6, said rolls having trun# nions 76 engaged Awith flanges 77 on the Seid been ings and rolls 75 guide the upper and intermediate ironing rolls in rectilinear pnths so that when they are retracted from the chnmbers and no portions of their cloth covering can vremain in Contact with the seid chambers. The' antit'riction rolls obviate the necessity of lubricating the slidn ing bearings l5 and 1G, so the-t there is no liulgiility of soiling the `goods by lubricating., vmateriel.

'lhe ironingr rolls are rotated by a driving butt it; through the'train of gears 79, 80,

fil. Sill, Sl, andtiti (l'ig. l). The gear i9 is attiched to the driving?r shstt. The fears S0 and di. are attached to e shaft 87 The nears and 83 are attached to e. shaft 88 :ilso jeurneled in bearings on, the, frame. The gears 8d, and nre attached re spectively to the roll shafts 2.1, 19 and 1T.

Erich ironing roll is constructed vas shown in detail by Figs. 7, 8, 9 and 10Which may he imderstood to represent the upper roll 18.

body of the roll is composed ot' e hollow i inetd. cylinder 90 yend heads 91 inserted. in

the ends of the cylinder and having flanges 92 bearing Aon seid ends. The heads 91 have hubs 93 attached by set screws 94 and keys 95 (Fig. l0) to the shaft 17. vSaid shaft is:

provided Within the cylinder 90 with hubs 96 attached to the shaft by set screws 97 and keys 98 (Fig. 9), fornily spaced from each other and from the heads 91, as indicated by Fig. 7. Each hub 96 has a head or enlargement 99 provided in eech of its four sides With dovetail guides 100, which are inclined relatively to the shaft 17 as shown by Fig. 8. With seidl guides are engaged dovetail. slides 101 formed on supporting blocks 102 having segmental outer faces 108 fitting the internal surface of the cylinder 90. The supthe hubs 96 being uni? porting blocks have tapped orifices engg-fv ing the threaded inner ends of tension rods 10%, the threaded outer ends of which pass freely through holes in guides 100, and caused to bind firmly against A the inner surface of the cylinder 90. The hubs 9G and supporting blocks 102 constitute expensible heads adapted to be supported b v the heads 91, and are provided with nuts 105 bearing on the Vouter sides of the heads 91.

the shaft While contracted, and expanded after the parte at points between the outer heads 91, so that are assembled. The ex-` Y' pended heads rmly support the cylinder v y the cylinder is rigid from end to end andY cannot be bent or sprung by the pressure of unusuelly thick parts of the 'goods against the periphery of the roll.

The hubs 93 are externally threaded and with their threaded portions are' engaged sleeves 106 having clamping flanges 107, the heeded edges 108 of which confine the inwardly bent portions of the cloth covers 24- ngainst the beveled edges 109'of the heads 91. rllhe rotation of the sleeves 106 thereforey v causes the flanges 107 to either secure or release the ends 'of the cloth cover.

Hereinafterv the levers 44 Lare termed chamberndjusting levers, the levers 50 and bearingncljusting levers, and the links 03, connections between the chambernc'ljusting levers, whereby they are caused to move -in unison. The shoes 49 are re terred to es supports for the lower chamber and the links 69ste referred to as movable means for preventing the lower chamber from tipping on the supports with which it is loosely connected. The chambers and 26 are hereinafter described es facing in opposite directions to concisely point out the fact that the chamber 25 is at one side of the roll 1B, while thc chamber 26V is at the opposite 'side of the 1011120. The

lower chercher 27, which feces nlpwerdlv 13@ 5nd is adapted to raise the goods to a oint above the lowest part of the lower ro enables the height of the series of rolls and of the machine as ,a whole to be reduced to the minimum, the goods passing. below'the level' if'the table 30 on ltheir vtvay thereto. The.

relative arrngement'of `rolls, in a seriele which is substantiall vertical although `somewhat:ii'elix'red ass own from afvertioal plane, contributes@ the reductionpf the height of 'this upper' roll 'and'o'f the vmachine as a whole and at the"'same time reduces the length of the'machine from -front .to rear as compared with a m'achinein which the rolls are arranged more nearly in a horizontal plane.- f

The table is located below the axis of I the roll 22 so that goods ,deliveredby the lower rollare free to swing outwardly from the periphery of said roll b gravitation-and drop uponv thetable, the ro 1y aving notendency to carry the goods upwardly and be- Y tweenlit and the roll 20.l p
